Plasticizers for Energetic Polymers

Energetic pol5nners are useful in rocket propellant binder compositions, as well as in propellant compositions for air bags in the automotive industry. They are, and formed from, poly(ether)s bearing pendant azide groups crosslinked without a catalyst by a diacetylene compound (42), or triazole and tetrazole pol5nners, respectively. 

High energy nitrate esters are used to plasticize the PU propellants. Butanetriol trinitrate is such a plasticizer (41,42). Other plasticizers for propellants are shown in Table 2.6.
